Who is Who

In the picture with the matching pooh-bear pajamas, Alex is on the left and Jordan on the right. In the picture with the blue pajamas, Jordan is on the left and Alex on the right. What surprises me though, is that if i didn't know who was who, I would say that in both pictures, the baby on the left looks the same. It really depends on the expressions that I capture as to who looks like who. It amazes me that these two boys can looks so different at times and so similar other times.
